に設けられている。BACKGROUND OF THE INVENTION Such a blower device having a blower shroud which surrounds the blower blades of the blower impeller and is attached to the blade tips is known from DE 28 26 697 A1. The blower impeller is supported by the internal combustion engine via the blower impeller axle, and a Sibelt wheel that runs one or more V-belts driving the blower impeller and other auxiliary equipment from the internal combustion engine drives this blower impeller. The ti1 plane is installed on the PM axle.

間と費用を伴う。Now, in blower impellers with surrounding blower shrouds, replacing a defective V-belt involves considerable difficulty depending on the length of the V-belt. Only such a V-belt, for example with a diameter larger than that of the blower shroud, is easily replaced by simply sliding it past the blower impeller for installation or removal. In contrast, a V-belt with a diameter smaller than that of the blower shroud is replaced only after the entire blower impeller has been removed, which involves considerable time and expense.

根車軸から同時に駆動することができる。The blower impeller l has a blower boss 2 on which radially projecting blower blades 3 are mounted. The blower blades 3 are surrounded by a blower shroud 4 which is connected to the blower blades 3 at the blade tips 5. It is not shown in FIG. 1 that the blower impeller 1 is rotatably supported on the end face of the internal combustion engine via a downstream-mounted blower impeller axle. A belt pulley for the V-belt 6 is mounted on the blower impeller shaft, and the blower impeller 1 is driven from the crankshaft via this V-belt. Via a further V-belt, auxiliary equipment on the internal combustion engine can be simultaneously driven from the blower blade axle.

落下する。In order to be able to install such a V-belt without removing the blower impeller 1, the blower shroud 4
is provided with a slit 7 extending in the axial direction. According to FIG. 1, the slit 7 is located in the circumferential area of the fan shroud 4, which extends between the two fan blades 3. - For installation, the heald 6 is inserted from the outside through the slit 7 between the two blower blades 3 and pushed to the blower boss 2. At this time, when the slit 7 is located above the blower impeller l, the belt 6 subsequently falls to the position shown by the solid line below the blower impeller.

しない支柱のこのような形状が好ましい。The interruption of the blower shroud 4 considerably reduces its strength. In order to be able to compensate for this loss of strength, according to FIG. 2, the shrouding plate pieces on both sides of the slot 7 are connected to the blower boss via one auxiliary vane 1 and 12, each configured as a support. has been done. The auxiliary vanes 11 and 12 provided in the immediate vicinity of the slit 7 may have other shapes. However, such a shape of the strut is preferred as it does not impair the efficiency of the blower impeller 1.

１２を省略することができる。Irrespective of this, as shown by the chain line in FIG. 2, the slit 7 is provided in the immediate vicinity of the blower blade 3, and, for example, the shroud plate piece on the left side of the slit 7 is directly supported via the blower blade 3, and the shroud It is also possible to support the piece 9 through special auxiliary blades 11. This allows the auxiliary blade 12 to be omitted.
第３図の実施例では、スリット７が送風機羽根３の半径
方向延長部に延びる囲い板部分１３に設けられている。In the embodiment of FIG. 3, the slit 7 is provided in a shroud portion 13 extending in the radial extension of the blower blade 3. In the embodiment of FIG.

うにすることができる。In the embodiment of FIG. 4, a slit 18 is provided between the blower blades 19 and 20 in the shroud portion 17 of the blower shroud. The slots h18 are arc-shaped in accordance with the axial course and contour of the blower blades. The longitudinal edges 21 and 22 formed by the slits in the shroud part 17 lie in the radial plane of the mutually facing vane surfaces 23 and 24 of the blower blades 1 and 20, respectively. Vertical edge 2
1 follows the progress of the blade surface 23 of the blower blade 19, and the vertical edge 2
2 follows the course of the blade surface 24 of the auxiliary blade 20. This allows the blades 19 and 20 as struts to extend over the longitudinal edges 21 and 22 over the entire axial section of the slot 18.
